72 | X | ÷ | ( | 100 | + | X | ) | = | 61 25 |
Multiply both sides of the equation by: | ( | 100 | + | X | ) |
72 | X | = | 61 25 | ( | 100 | + | X | ) |
72 | X | = | 61 25 | × | 100 | + | 61 25 | X |
72 | X | = | 244 | + | 61 25 | X |
72 | X | − | 61 25 | X | = | 244 |
1739 25 | X | = | 244 |
X | = | 244 | ÷ | 1739 25 |
= | 244 | × | 25 1739 |
X | = | 6100 1739 |
X | = | 3.507763 |
